7494697b8c g-dyntab.ads, [...]: Remove incorrect assertion.
2017-04-27  Bob Duff  <duff@adacore.com>

	* g-dyntab.ads, g-dyntab.adb, g-table.ads: Remove incorrect assertion.
	If the table grows and then shrinks back to empty, we won't necessarily
	point back to the empty array. Code cleanups.
	* sinput.ads: Add 'Base to Size clause to match the declared
	component subtypes.
